Thanks - for the prompt responses I also did a search but no specific info. Certainly no issue with access. I had looked at the OW site and as quoted by Aleks makes no mention of the coupons. I have to say this was the first time I have had an issue at PHL and I have done many AA Domestic only flights.

At DFW ended up with four coupons as my flight to ANC moved from Term D to Term C due to weather.
